WebDialogs popped out a new beta of their Unyte product yesterday. It uses peer-to-peer technology to upgrade the current product, providing a better and faster experience when both parties are Unyte users.
My personal experience using the current Unyte product (it's how iotum does web conferencing) has been fabulous.
Webdialogs is looking for testers. If you use web-conferencing at all, you owe it to yourself to check this product out. Head to http://beta.unyte.com to download it.
